1/150. Dacryolith formation around an eyelash retained in the lacrimal sac.A dacryolith was discovered in the lacrimal sac during a dacryocystorhinostomy for chronic dacryocystitis in which there was mucocele formation. Morphological examination confirmed the presence of an eyelash at the centre of the stone and electron microscopy demonstrated the presence of fungi (candida sp.) in a matrix which was of markedly vairable morphology. The mechanism by which a hair enters the punctum and passes along the canaliculus may be attributed to the step-like pattern of ridges on the surface of a hair. The directional nature of these ridges dictates preferential movement towards the root end of the hair and prevents movements in the opposite direction.- - - - - - - - - - ranking = 1keywords = stone (Clic here for more details about this article) |
2/150. Impacted papilla minor stone in pancreas divisum causing severe acute pancreatitis: a case for early ERCP in acute pancreatitis of unknown origin.This is the first description of severe acute pancreatitis in pancreas divisum caused by a solitary stone impacted in the minor papilla. Recovery was rapid after diagnostic endoscopic retrograde cholangiopancreaticography (ERCP) and endoscopic stone removal. Since other etiological factors accounting for the acute pancreatitis were carefully excluded, it seems that obstruction of the minor papilla by a solitary pancreatic concrement was the most likely cause of acute pancreatitis. This case report demonstrates the diagnostic importance of early ERCP in cases of etiologically unexplained acute pancreatitis.- - - - - - - - - - ranking = 6keywords = stone (Clic here for more details about this article) |
3/150. Hepatic subcapsular hematoma after extracorporeal shock wave lithotripsy (ESWL) for pancreatic stones.We present a patient with complication of huge hepatic subcapsular hematoma after extracorporeal shock wave lithotripsy (ESWL) for pancreatic lithotripsy. The hematoma measured 78-110mm. angiography showed a subcapsular hematoma, rather than a hematoma in the liver. In the arterial phase, the distal end of the small vessel showed spotty opacification similar to microaneurysma, suggesting that it was an injury caused by separation of the liver and its capsule, caused by the shock waves. The portal vein and hepatic vein were normal. After 8 weeks of conservative therapy, the hematoma was gradually absorbed and the patient was discharged. Eight months after the accident, the hematoma had decreased to 40mm in size. After 20 months, it was completely absorbed. The reported rate of renal subcapsular hematoma after ESWL for renal or ureter stones is 0.1%-0.7%. To date, however, only five cases of hepatic subcapsular hematoma after right renal stone disintegration have been reported. This is the first report of hepatic subcapsular hematoma after ESWL for pancreatic stones.- - - - - - - - - - ranking = 7keywords = stone (Clic here for more details about this article) |
4/150. afferent loop syndrome presenting as enterolith after Billroth II subtotal gastrectomy: a case report.We present a rare late-onset (after 24 years) complication of gastric surgery with a combination of afferent loop syndrome associated with a large duodenal stone. The patient, who had undergone Billroth II partial gastrectomy for benign ulcer 24 years before, developed abdominal pain in the right upper quadrant, associated with nausea, vomiting, and high grade fever. Abnormal laboratory values included elevated liver function test, suggesting a pressure-related phenomenon. leukocytosis and a high level of platelets were also found. Only computed tomography and endoscopy of the upper gastrointestinal tract confirmed the diagnosis of a huge stone in the dilated duodenal afferent loop. To our knowledge, a case like this has not been reported previously in the literature.- - - - - - - - - - ranking = 2keywords = stone (Clic here for more details about this article) |
5/150. Endoscopic pancreatic sphincter balloon dilation for effective retrieval of pancreatic duct stone.To facilitate pancreatic stone retrieval, four patients with chronic pancreatitis and pancreatic stones underwent endoscopic pancreatic sphincter balloon dilation (EPSBD) rather than pancreatic sphincterotomy. Extracorporeal shock wave lithotripsy combined with endoscopic removal was carried out in three patients. Stone removal following EPSBD was completely successful in all four patients. patients showed no severe complications during the dilation procedure. In one patient, to prevent pancreatitis, an endoscopic nasopancreatic drain was placed for 1 week after EPSBD. Compared with pancreatic sphincterotomy, EPSBD can be performed safely in patients with chronic pancreatitis to assist in the extraction of pancreatic duct stones. Use of the EPSBD procedure in cases of chronic pancreatitis provides a useful approach to improve endoscopic clearance of pancreatic duct stones.- - - - - - - - - - ranking = 8keywords = stone (Clic here for more details about this article) |
6/150. Vaginal calculi in a young woman.A case of a large vaginal stone in a 26-year-old woman is presented. Vaginal stones are relatively rare. Various causes can lead to vaginal stone formation. In our case, the calculi was due to vaginal outlet obstruction in childhood. The diagnosis is usually easy to be done. In our patient, X-ray films using frontal and lateral views of the urinary system permitted to establish the right diagnosis. Treatment can vary, depending on the cause of the stone formation and the consistency of the calculi. In this case, the treatment was surgical with simple evolution. It permitted a normal social and sexual life to this young patient.- - - - - - - - - - ranking = 4.0030981467896keywords = stone, urinary (Clic here for more details about this article) |
7/150. Primary vaginal stone in an 11-year-old recumbent girl.Primary vaginal stones are extremely rare, particularly in young women. We describe the occurrence of a primary vaginal calculus in a severely retarded 11-year-old girl who was not diagnosed until she was examined using computerized tomography. We postulate that the calculus was formed as a consequence of urinary contamination of the vagina in association with incontinence and prolonged maintenance in a recumbent posture.- - - - - - - - - - ranking = 59.424393466676keywords = calculus, stone, urinary (Clic here for more details about this article) |
8/150. Perforation of acute calculous Meckel's diverticulitis: a rare cause of acute abdomen in elderly.Complications of the Meckel's diverticula are well-known and defined. However, acute inflammation and perforation secondary to a calculus is a rare clinical presentation. A case of acute calculous Meckel's diverticulitis with perforation in a 58-year old man is presented and possible pathological conditions are discussed. Location of the perforation, apical microscopic focal ulcers, and ischaemic changes in the diverticulum remind the pathogenesis comparable to that of acute calculous cholecystitis. This case report with major complications related to Meckel's diverticulum strengthens the concept of prophylactic resection of Meckel's diverticulum in adults, incidentally discovered at laparotomy.- - - - - - - - - - ranking = 27.210647659943keywords = calculus (Clic here for more details about this article) |
9/150. portal vein phlebolithiasis found post-liver transplantation in the native liver of a child with biliary atresia.biliary atresia is defined as partial or total obliteration of the extra-hepatic bile ducts. In advanced cases, liver transplantation (LTx) is considered the most appropriate treatment. This report describes a female patient whose biliary atresia and subsequent cirrhosis required LTx at 1 yr of age. Macroscopic inspection of the hilar region of the native liver post-Tx revealed the formation of a pouch in the hepatic duct and a stone in the lumen of the portal vein. x-ray diffraction analysis showed that the stone was composed of cholesteryl cinnamate, gluconic acid phenylhydrazide, Na beta broma-allyl mercaptomethyl penicillinate, and Al2O3 crystals. While the cholesterol component is a known element of gallstones, we attributed the Na beta broma-allyl mercaptomethyl penicillinate to the patient's drug therapy. Our literature search revealed no previous record or crystallographic analysis of portal vein phlebolithiasis. In this report we describe this rare finding.- - - - - - - - - - ranking = 3keywords = stone (Clic here for more details about this article) |
10/150. A calculus within an anal fistula tract in a diabetic patient.A non-insulin dependent diabetic patient with a chronic anal fistula underwent fistulectomy. At operation a calculus was discovered. The patient had an uneventful recovery and healing of the wound in 4 weeks duration. The only case reported previously was in a nondiabetic patient and interestingly from this department.- - - - - - - - - - ranking = 136.05323829972keywords = calculus (Clic here for more details about this article) |
